We are the fattest country in the world already and consistently score lower on most measures of population health than countries with universal healthcare. How much more "financial incentive" do we need to get ourselves healthy, exactly?

Just like smoking obesity is caused by sophisticated marketing campaigns by manufacturers. And engineering the product to make it more addictive. And they know it makes people unhealthy but they don't care, just make more money.

Not that people shouldn't take personal responsibility. They certainly suffer the consequences.
